The valves, which are all' similar, are const'ituted by a. ,metal cylinder `.withjthin wall..l

(v2 having the same diameter .y as thek inner diameter-of the sleeve fg. Each valvey has four orifices; three of them have the same dimensionsas ythoseofthe sleeve .g the;

fourth 21 is ofthe same width as the preceding but its length is three times greater to allow it to cause communication at the lrequired moment of the coupled orifices of the sleeve which' correspond `-to'`*-it.

Tlusa's shownin "Figsj, Tand 8 thelarge orifice 21 and the small orifice 22which is opposite' it fon the; same sidejof the Aaxial plane, are separated eand'isolated from thev rest of the valve by a partition 23.
